FEED-CUTTER.

SPECIFICATION forming part of Letters Patent No. 345,078, dated July 6,1886.

Application filed January 18, 1886. Serial No. 188,845. (No model.)

T0 all whom t may concern:

Be it known that we, CHARLES SILBER- ZAHN and CHARLES A. SILBERZAHN, ofWest Bend, in the county of Washington, and in the State of Wisconsin,have invented certain new and useful Improvementsin Feed-Cutters; and wedo hereby declare that the following is a full, clear, and exactdescription thereof.

Our invention relates to feed-cutters; and it consists of certainpeculiarities of construction, as will be fully described hereinafterwith reference to the accompanying drawings, in Which- Figure lA is aside elevation of a portion of a feed-cutter embodying our invention;Fig. 2, a top plan View; Fig. 3, a detail showing the geai` and aportion of the feed-rolls in front elevation; Fig. 4, a detail view ofthe shifting-frame, and Fig. 5 a detail view illustrat` ing theconstruction ofthe shaft for the clutchpinion and gear-wheel.

A represents the front standard, and B one of the side pieces of asupporting-frame for the feed-box C andl operating mechanism of themachine. J ournaled in suitable bearings, a, is a shaft, D, having`secured thereto heads b, for the knives c, the end of this shaft on oneside of the machine being provided with a pinion, E, and adapted toreceive a crank, and to the other end of said shaft is intended to bekeyed a flywheel provided with a bandpulley, for connecting theoperative mechanism with a suitable driving-power.

F F are the feeding-rollers, of the usual construction and adjustmentwith relation to the feed-box and knives. The journal of the upperroller, F, has keyed thereto a gearwheel, G, which meshes with a loosepinion, H, journaled upon a short shaft, f, extending outpfrom thecutter-box on the crank side of the machine. Journaled to the cutter-boximmediately below the pinion H and meshing therewith is another loose'pinion, I, which also meshes with a gear-wheel, K, keyed to the journalh of the lower feeding-roll, F. This journal h is also designed toreceive the sleeve i of an angle-arm, L, said arm having its forward orfree end operating in a guidebracket, 7c, secured to the side piece, B,of the 5o supporting-frame. The rear end of the arm L is provided withan inwardly-projecting stud, m, designed to'engage an arch-shaped slot,n, in the lower or segment portion of av lever, M. This lever ispivotally connected to a vertical bracket, O, the latter being securedto the side piece, B, of the supportingframe, and the slot in said leveris provided with sockets `o o at its extremities, adapted to receive thestud m and limit the movement of the arm L in either a forwardor'backward direction. To the lower feed-roll journal, h, is also fittedthe front end of a straight arm, P, having its other end socketed inflanges p p on the respective rear portions of the arm L, and atriangular arm or plate, R, said parts L, P, and Rbeing united by abolt, 1', to form Ia frame, though, if found more desirable, these partsmay-constitute a single casting. The triangular plate or arm R carries apinion, S, which meshes with a gear-wheel, T, having its shaft composedof a bolt, s, carrying a sleeve, t, said bolt being adjustable in curvedslots u u', respectively formed in the parts .L R, and the sleeveadapted to fit the bore of the gear-wheels hub; rlhis gearwheel T hasthe inner end of its hub formed with recesses o, adapted to engageprojections o upon the outer face of a removable pinion, V, adapted to tupon the sleeve t of shaft of said gear-wheel.

In order to permit of the machine being geared to vary speed, two ormore sizes ot" the pinion Vare designed to accompany each cutter, theslots u u in the parts L R permitting the shaft designed to carry one ofthese pinions and the gear-wheel T to be adjusted so said pinion may bebrought into mesh with the gear-wheel K, keyed to the journal of thelower feeding-roll, F.

The above-,described series of pinions and wheels form the entiregearing forour cutter, and are operatively arranged with relation Ytoeach other upon a single side of the machine, this being considered ofmaterial advantage in the matter of compactness and convenience.

When the lever M is in the position illustrated by Fig. l, the machineis out of gear, though the knives may be revolved while thefeeding-rolls remain stationary.

It will be noticed that the frame, composedA IOO of the parts L P R, isentirely supported at but two points, said points being the journal h ofthe lower feed-roll, F, and the arcshaped slot 'n in the segment endofthe lever M. The frame being thus virtually on a pivot can be readilyshifted at the will of the operator. being pivoted on'the journal h,`bymoving the upper end of the lever forward the frame is tilted on itspivot, (the journal In) and the pinion S is caused to mesh with pinionE, and pinion V with gear-wheel K. The pinion S being always in meshwith the gear-wheel T, motion is imparted to the lower'feeding-roll, F',through the medium of the pinion V, having a clutch-connection with saidgear-'wheel T, and meshing with a similar wheel, K, on the journal ofthe said lower` roll. This gearwheel K meshes with the pinionLjournale'd to the cutter-box, and said pinion with another one, H, alsoj ournaled to the cutter-box, which in its turn comes into mesh wit-hthe gear-wheel G on the upper feed-roll, F. The machine is now in gearfor cutting feed,which latter is carried from the boxV C to the knives cby the movement of the rolls F F', and to retain the several parts inrelation-to each other when the lever is operated to bring them inoperative contact, as above described, the stud m on the angle-arm Lenters the socket o at the forward extremity of the slot a of saidlever,y and by this engagement the stud is not liable t0` becomedisengaged from its corresponding socket Aunless the lever is forciblyoperated, upon. To reverse the action of the feed-rolls F F', theoperator throws back the lever uM,v thereby causing an upward movementof the pivotal frame to throw the pinion S out of gear with the one E onthe knife-shaft D, and bringing the gear-wheel T into mesh with saidpinion E. As this movement' is accomplishedthe stud m of the angle-arm Llocks lin the socket o of the arc-shaped slot in the lever. The pinionS, though meshing with the gearwheel T, runs idle when the lever isreversed, while theother pnions and gears remain in the same position aswhen the machine is feeding .to the knives, their position beingunchanged, no lmatter what may be fthe move-vv ment of theshifting-lever and pivotal frame.1

By the construction and arrangement of the gearing and the shiftingmechanism, as above described, the feeding-rollers Ycan be instantlyreversed or stopped by a single jerk of the lever while the knives arein`full motion, there being no springs or locking devices to raisebefore said lever can be moved.

The above feature is deemed of particular advantage in case anything ofa damaging character should get into the machine. Another advantage liesin the fact that the rollers can be stopped while getting up motion ofthe knives,` and the faster said knives run the easier the severalparts'w-ill gear when the shifting-lever is operated.

The framev slot and a stud, the latter engaging a suitably- `slottedlever, a straight arm connected to said journal, and a triangular arm orplate carrying a pinion and gear-wheel and provided with'a curved slotto register with the one in the angle-arm, substantially as and for thepurpose set forth.

2. In a feed-cutter, a pivotally-connected shifting-lever having itslower portion in the form of a segment and provided with an arc shapedslot, in combination with a pivoted frame connected with said lever andprovided with a pinion and gear-wheel to be thrown in and out of gearwitha pinion on the knifeshaft of said feed-cutter, substantially as andfor the purpose iset forth.

3. In a feed-cutter, the combination of suitable gear-fwheelsrespectively keyed to the journals of the upper and lower feed-rolls,loose pinions journaled on short shaftsA projecting from one side of thecutter-box, and a ment and provided with an arc-shaped slot z designedto engage astud upon an arm of the pivoted frame, all constructed andarranged to operate substantially as and for the purpose set forth.

4. In a feed-cutter, the driving-gear located entirely upon one side ofthe machine, in combination with a'shifting-gear for reversing orstopping-the action of said lnachine, composed ofv a frame ,pivotallyconnected to the lower feed-roll journal and carrying a pinion andgear-wheel, the shaft of the latter' consisting of a bolt and sleeveadjustable in said frame, a removable clutch-pinion journaled on saidadjustable shaft,and a segment-lcv er pivotally connected to the gearside of said machine to vengage the pivoted frame, substantially as andfor the purpose set forth.

In testimony that we claim the foregoing 'we have hereunto set ourhands, at West Bend, in the county of Washington and State of Wisconsin,in the presence of two witnesses.
